The email address registered with your WordPress.com account is your unique identifier. You will notice that when you sign up, we do not require any other information. As such, this is how we are able to verify ownership of blogs and accounts; it is very important to remember and update it as necessary.
Once you’ve entered a new email address and saved the change, you’ll receive two emails: one email will go to the original email address on the account as a notification of the request and the other will go to the new email address with a confirmation link. You will need to click the confirmation link to complete the process to change the email address.
If you send us a note requesting help with accessing your account/blog, we will require an email from the address registered with the account as this proves account ownership. Otherwise, we cannot help.
Early on, WordPress.com allowed users to create several user accounts using the same email address. This created several problems with account management, so we had to make changes and require each user account to use a unique email address. This means that accounts may not share email addresses.
Issues Changing your Email Address
If you attempt to change your account email address and find that it never sticks after saving the changes, the issue is quite simple. The email address you are attempting to use is probably associated with another WordPress.com account. Because the email address is the unique identifier of all users, each address can only be associated with one WordPress.com account. Thus, if you attempt to change it, it will not allow you to do so.
The remedy is just as simple. You must log in to the account currently holding your desired email address and change it to something else. This will allow you to free up the email address that you want to use. Once the address is free to use, log in to your primary account and change the email address in your user profile (what you were originally trying to do). It may take a little while for the address to completely free itself up.
If you requested the change but did not receive the email confirmation to finalize it (or the confirmation did not work), please contact support.
When you leave a comment on a blog at WordPress.com, and if you are logged in, your email address is made available to the owner of the blog when they see your comment. This is the same as you see when people comment on your blog.
If you are uncomfortable with that, you must log out of WordPress.com before leaving a comment. Even then you will have to leave an email address but it will be your choice as to what you enter. Some blogs will require you to be logged in to make a comment – in that case, you cannot.
If you leave a comment and realize you were logged in, please do not contact support – nothing can be done. We will not, under any circumstances, edit the comments on our users’ blogs at your request.
